\(\left(y+\frac{1}{5}\right).\frac{3}{7}=\frac{5}{14}\)
\(\left(y+\frac{1}{5}\right)=\frac{5}{14}:\frac{3}{7}\)
\(\left(y+\frac{1}{5}\right)=\frac{5}{6}\)
\(y=\frac{5}{6}-\frac{1}{5}\)
\(y=\frac{19}{30}\)
Vậy \(y=\frac{19}{30}\)
(y + 1/5) . 3/7 = 5/14
y + 1/5 = 5/14 : 3/7
y + 1/5 = 5/6
y = 5/6 - 1/5
y = 19/30
Chúc bạn học tốt ^^
\(\left(y+\frac{1}{5}\right).\frac{3}{7}=\frac{5}{14}\)
<=> \(y+\frac{1}{5}=\frac{5}{14}:\frac{3}{7}=\frac{5}{14}.\frac{7}{3}=\frac{5}{6}\)
<=> \(y=\frac{5}{6}-\frac{1}{5}=\frac{19}{30}\)
Chúc bạn học tốt
\(\left(y+\frac{1}{5}\right).\frac{3}{7}=\frac{5}{14}\)
\(\Rightarrow y+\frac{1}{5}=\frac{5}{14}:\frac{3}{7}\)
\(\Rightarrow y+\frac{1}{5}=\frac{5}{6}\)
\(\Rightarrow y=\frac{5}{6}-\frac{1}{5}\)
\(\Rightarrow y=\frac{19}{30}\)
Vậy \(y=\frac{19}{30}\)
